Find The Value Of X.4x + 52x + 21, Smby Help Me Wit Dis Pls

Answers

Answer 1

Answer: x = 8

Step-by-step explanation:

4x + 5 = 2x + 21

4x + 5 - 2x = -2x + 2x +21 (Subtract 2x from both sides)

2x + 5 = 21

2x + 5 - 5 = 21 - 5 (Subtract 5 from both sides)

2x = 16

2x/2 = 16/2 (Divide both sides by 2)

x = 8

Answer:

  (b)  g(x) = -f(x+3)

Step-by-step explanation:

The dashed-line graph is a reflection over the x-axis and a left-shift by 3 of the solid-line graph. To reflect the function over the x-axis, negate it.

  f(x) ⇒ -f(x) . . . . reflected over the x-axis

To translate a function to the right horizontally by "h" units, replace x in the function with (x-h). Here, we want a left shift, so h=-3. That is, x is replaced by (x+3).

Both transformations together give you ...

A rectangle has a length of 3x + 7 and a width of 2x. If the perimeter of the
rectangle is 94 units, what is the length of the rectangle.

Answers

Answer:

The length of the rectangle is 31.

Step-by-step explanation:

We have that the length (L) and width (W) are:

[tex] L = 3x + 7 [/tex]

[tex] W = 2x [/tex]

The perimeter of the rectangle is given by:

[tex] P = 2W + 2L [/tex]

[tex] 94 = 2(2x + 3x + 7) [/tex]

[tex] 94 = 10x + 14 [/tex]

[tex] x = 8 [/tex]

Now, we can calculate the length of the rectangle:

[tex] L = 3x + 7 = 3*8 + 7 = 31 [/tex]        

         

Therefore, the length of the rectangle is 31 units.

I hope it helps you!

Taylor bought a painting for 1 million yen while in Japan. At the time, exchange rate was 1 dollar to 126 yen. If a friend offers $2,000 dollars for the painting would Taylor profit?

Answers

Answer:

No, she would not profit.

Step-by-step explanation:

1 dollar = 126 yen

x = 1000000 yen

1000000 ÷ 126 = $7, 936.51

$2,000 is not enough to cover the value of the painting as Taylor would lose over $5,000. So, she would not profit.

==========================================================

Explanation:

Sides ED and FD are the same length due to the red tickmarks.

The angles opposite these side lengths, angle E and angle F, are congruent as well. So angle F is also x.

For any triangle, the three angles always add to 180

F+E+D = 180

x+x+74 = 180

2x+74 = 180

2x+74-74 = 180-74 .... subtract 74 from both sides

2x = 106

2x/2 = 106/2 ... divide both sides by 2

x = 53

As a check,

F+E+D = x+x+74 = 53+53+74 = 180

which verifies the answer.

The graph of equation is in image.

What are linear equations?

When a linear equation is graphed, it always results in a straight line because each term has an exponent of 1. This is why it is referred to as a "linear equation."

There are linear equations with one and two variables, respectively.

Given equations 2x + 3y = 5

4x - 5y = -1

for equation 1

2x + 3y = 5

x    1     -2    4

y    1      3    -1

coordinates for equation 2

4x - 5y = -1

x    1     2    -4

y    1     1.8   -3

and the intersection point of equation is (1, 1)

Hence the graph of equation is intersecting at (1, 1).
